ROLLING-MILL.

SPECIFICATION forming partof Letters Patent No. 284,700, dated September11,1883.

Application filed December 27, 1882. (No model.)

To all whomit may concern:

Be it known that I, SAMUEL T. NVILLIAMs, of Troy, in the county ofRensselaer and State of New York, have invented certain new and usefulImprovements in Rolling-Mills; and I dohereby declare the following tobe a full, clear, and exact description of the invention, .such as willenable others skilledin the art to which it pertains to make and use thesame; My invention relates to an improvement in mills for rollingrailroad-rails, bars, plates,

and all masses of metal of similar shape.

Rolling-mills as heretofore constructed maybe classified under threeheads: first, those I 5 having two rolls rotating in the same direction;second, those having three rolls, the upper and lower rolls beingrotated in opposite directions; and, third, those having two rollsarranged to be reversed in the direction of their rotation between thesuccessive passes of the article being rolled. Mills of the first classare objectionable 011 account of the great eX- penditure of time andlabor involved in idly returning the article being: rolled from the 2delivery to the entering side of the rolls. On the other hand, mills ofthe second class are objectionable on account of the expenditure of timeand labor necessarily attendant upon raising and lowering the articlebeing rolled to enter it between the upper and lower rolls,

5 while mills of the third class are objectionable on account of thetime involved in reversing the rolls between the successive passes ofthe article being rolled, and also on account of the 3 5 great wear onthe rolls and their associated mechanism which the reversing entails.

My invention com'prehends the construction of a rolling-mill of thecharacter designated which shall obviate the objections incident to 40these classes of mills, above referred to, and which shall, combinesimplicity and cheapness of construction with durability and efficiencyin use. p

\Vith these ends in view my invention con- 5 sists in certain details ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

The accompanying drawing represents a plan view of a rolling-millembodying my in vention.

A and B respectively represent the upper rolls of two sets of rollsplaced end to end and independently rotated in opposite directions, asindicated by arrows on the fly-wheel (I, by power applied through thepinions D.

A table, E, to be hereinafter designated as the entering-table, andconsisting of aseries of rollers, F, mounted in suitable frame-work, islocated in front of the entering side of the rolls A, several. or all ofthe rollersF being rotated in the direction of the said rolls by powercommunicated to them through a shaft, G, provided with gears H, arrangedto mesh with similar gears, I, attached to the rollers.

A table, E, to be hereinafter designated as the delivery-table, andsimilar in construction to the entering-table E, is located in front ofthe delivery side of the rolls A, and adapted to receive the articlebeing rolled as it is delivered from them, No provision is shown forrotating the rollers F of this table; but this may be provided for, iffound desirable. Cylinders J, operating from the outer edge of and atright angles with the said delivery-table, are provided with suitablewater or steam connections, (not herein shown,) according to the motoremployed in actuating them. The outer ends of the piston-rods K of thesaid cylinders are adapted to engage with the articles delivered ontothe table E, and move them transversely'over it and onto theentering-table L of the rolls B, which, as before described, rotate inreverse direction from. the rolls A. The said entering-table L, which issubstantially the same in construction as the tables E and E, isparallel with and located in or about the same horizontal plane as thelatter. The rollers M of this table are rotated in the direction of therolls B by power transmitted to them through the shaft N, provided withgears O, and meshing with similar gears, P, attached to the rollers. Thearticles being rolled are delivered from the rolls B onto thedeliverytable L, the same being substantially the same in constructionas the tables already described,

and parallel 'with and located in or about the same plane as theentering-tableE of the rolls A. Cylinders J, operating from the outeredge of and at right angles with the said delivery-table L, areconnected with suitable IOO steam or water mains, (not herein shown,)according to the motor employed in actuating them. The outer ends of thepiston-rods K are adapted to be engaged with the articles ,deliveredonto the table L by the rolls B and ment of rolls, tables, and thedevices for moving the article being rolled, the transit of the two setsof rolls is made very rapidly andwith comparatively little manualintervention, the

article being reduced being passed through each set of rolls once inevery uninterrupted circuit of the tables. \Vhile it is apparent thatthe article to be rolled may be started from either of theentering-tables, let it be assumed, for the purpose of illustration,that it is started from the entering-table E of the rolls A, throughwhich it passes, being delivcred onto the delivery-table E, from whichit is immediately transferred to the enteringtable L of the rolls B bythe piston-rods K. From the said table L it is passed through the rollsB and delivered onto the delivery-table L, from which it is transferredby the pistonrods K to the table E, from which it first started, thearticle being continued in the circuit of the tables, as described,until it is reduced to the desired form. Of course it is not necessaryto pass the article being rolled successively through the two sets ofrolls, for it maybe returned idly over and repassed through either setof rolls as many times as need be.

In the improved mill herein described the wear of the mechanism, thetime elapsing between the successive passes, and the labor ofmanipulation are reduced to the minimum, whereby all operations under itare cheapened and facilitated. \Vhile the arrangement of placing therolls of the two sets end to end is probably more practical than anyother, they may be placed at any angle desired. Again, the invention isnot limited to the devices shown for transferring the article beingrolled from the delivery to the entering tables of the respective setsof rolls, for any other suitable devices may be employed instead. N oris the invention restricted to the particular construction of rolls,tables, and associated mechanism herein set forth. I would thereforehave it understood that I do not limit myself to the construction andcombination of parts herein shown and described, but hold myself atliberty to make such slight changes and alterations as fairly fallwithin the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An improved rolling-mill, consisting of two sets of rolls arranged torotate in opposite directions, of stationary entering and deliverytables for each set of rolls, and ofmeans for transferring the articlebeing rolled transversely over the delivery-tables, and onto theentering-tables adjoining them, substantially as set forth.

of the delivery-tables, and arranged to transfer the article beingrolled transversely over them and onto the adjoining entering-tables,

substantially as set forth.

3. An improved rolling-mill, consisting of two sets of rolls arranged torotate in opposite directions, of stationary entering anddelivery tablesfor each set of rolls, and of pistons operating from the outer edges ofthe delivery-tables, and arranged to transfer the article being rolledtransversely over them and onto the adjoining entering-tables,substantially as set forth.

4. An improved rolling-mill, consisting of two sets of rolls arranged torotate in opposite directions, of stationary entering and deliverytables for each set of rolls, said tables being composed of rollersmounted in suitable frames, of means to rotate the rollers of theentering-tables in the direction of their respective rolls, and of meansfor transferring the article being rolled transversely over thedelivery-tables and onto the entering-tables adjoining them,substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
